    1. Delivers 80W
    2. Delivers 45W
    3. Absorbs 80W
    4. Absorbs 75W
Correct Option: B

The given circuit can be redrawn as shown below

KCL at point A

VA – 0
+
VA – 15
= 3
55

or VA
1
+
1
= 3 + 3
55

or VA =
6 × 5
= 15 V
2

Now, Power = VA ×
V1
= 15 ×
15
= 45 W
55

Positive sign of power indicates that it delivers 75W power.
